Abstract
A method for protecting a metal during an annealing process, the metal being in the form of a coil or sheets, including placing a protective film between adjacent surfaces of the wraps of the coil or of the sheets, such that the protective film separates the adjacent surfaces of the metal. The metal is subjected with the protective film to the annealing process, the protective film being resistant to temperatures between 200° C. and 360° C. A metal product is obtained by this method.
